Problems solved by technology

However, there is no reinforcing structure in the cavity formwork member, so the overall strength and rigidity of the cavity formwork member are relatively poor, and the cavity formwork member is prone to damage. After being applied to the cast-in-place concrete hollow floor, it is also Unable to participate in the force bearing and transmission of the hollow floor

Embodiment Construction

[0050] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0051] As shown in the accompanying drawings, the present invention includes an upper plate 1, surrounding side walls 2, and lower bottom 3, and the upper plate 1, surrounding side walls 2, and lower bottom 3 form a polyhedron cavity formwork member, and is characterized in that the cavity mold At least one stiffening rib 5 is arranged inside the shell member, and the stiffening rib 5 is supported on the formwork 6 and the superimposed layers to form the inner plate of the double-layer plate. In the accompanying drawings, 1 is the upper plate, 2 is the surrounding side wall, 3 is the lower bottom, 4 is the pick plate, and 5 is the stiffener plate. In the following drawings, those with the same number have the same description. As shown in Figure 1, the upper plate 1, the surrounding side walls 2 and the lower bottom 3 enclose a polyhedral cavity formwor...

Abstract

The present invention relates to a hollow cavity form member for pouring concrete. It includes upper plate, peripheral side wall and lower bottom. Said upper plate, peripheral side wall and lower bottom are connected together and formed into a polygonal hollow cavity form member. It is characterized by that in the hollow cavity form member interior at least one rib-stiffened plate is set, said rib-stiffened plate is supported on the form panel of inner plate of double-layer plate formed from form panel and laminated plate. Said hollow cavity form member is applicable to construction of cast-in-situ reinforced concrete or prestressed reinforced concrete hollow floor, roof, wall body, foundation baseplate and open-web bridge. Specially it is applicable to construction of hollow beamless floor.

Description

[0001] This application is a divisional application of an invention patent application with an application date of August 4, 2003, an application number of 03143760.5, and a title of "a cavity formwork component for cast-in-place concrete". (1) Technical field [0002] The invention relates to a cavity formwork component for cast-in-place concrete. (2) Background technology [0003] At present, the cast-in-place concrete hollow floor is a widely used floor structure. The lightweight permanent tire molds filled in it include various hollow tubes and boxes, and the boxes are hollow or solid. For example, the patent No. ZL99249798.1, which the applicant applied for on November 29, 1999, is a utility model patent named "fiber-reinforced thin-walled member for reinforced concrete filling", which discloses a thin-walled formwork member, including an upper plate, The surrounding side walls, the lower bottom, and the upper plate, the surrounding side walls and the lower bottom form ...
